    简介:FRED作为COM组件可以实现与Excel、VB、Matlab等调用来完成庞大的计算任务或画图,本文的目的是通过运行一个案例来实现与Matlab的相互调用,在此我们需要借助脚本来完成,此脚本为视为通用型脚本。 SF,:jpt`Z+  
    63Gq5dF  
    配置:在执行调用之前,我们需要在Matlab命令行窗口输入如下命令: ;NdH]a {  
    enableservice('AutomationServer', true) 0,DrVGa  
    enableservice('AutomationServer') >L4F'#I  
    Y8v[kuo7  
    结果输出为1,这种操作方式保证了当前的Matlab实体可以用于通信 _!DH/?aU

    在winwrp界面,为增加和使用Matlab类型的目录库,我们需要如下步骤: # M/n\em"X  
    1. 在FRED脚本编辑界面找到参考. *(q?O_3,b  
    2. 找到Matlab Automation Server Type Library X coPkW  
    3. 将名字改为MLAPP 8Z9>h:c1

    在Matlab里面有两种常用的数据发送选项PutWorkspaceData 及PutFullMatrix,PutWorkspaceData适用于存储一般的数据在工作区,并赋予其为变量,PutFullMatrix试用于复数数据。 e8xq`:4Y

    现在将脚本代码公布如下,此脚本执行如下几个步骤: ij-'M{f  
    1. 创建Matlab服务器。 @U5gxK*  
    2. 移动探测面对于前一聚焦面的位置。 %?gG-R  
    3. 在探测面追迹光线 Tt~[hC h  
    4. 在探测面计算照度 |w*s:p  
    5. 使用PutWorkspaceData发送照度数据到Matlab E:**gvfq  
    6. 使用PutFullMatrix发送标量场数据到Matlab中 zqNzWX  
    7. 用Matlab画出照度数据 ^t gjs$M|  
    8. 在Matlab计算照度平均值 6X h7Bx1  
    9. 返回数据到FRED中 ?|W3RK;
